Check Digit Verification of cas no

The CAS Registry Mumber 66499-25-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,9 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66499-25:
(7*6)+(6*6)+(5*4)+(4*9)+(3*9)+(2*2)+(1*5)=170
170 % 10 = 0
So 66499-25-0 is a valid CAS Registry Number.

Decatungstate-Catalyzed C(sp3)-H Sulfinylation: Rapid Access to Diverse Organosulfur Functionality

Bissonnette, Noah B.,Macmillan, David W. C.,Sarver, Patrick J.

supporting information, p. 9737 - 9743 (2021/07/19)

Here we report the direct conversion of strong, aliphatic C(sp3)-H bonds into the corresponding alkyl sulfinic acids via decatungstate photocatalysis. This transformation has been applied to a diverse range of C(sp3)-rich scaffolds, including natural products and approved pharmaceuticals, providing efficient access to complex sulfur-containing products. To demonstrate the broad potential of this methodology for the divergent synthesis of pharmaceutically relevant molecules, procedures for the diversification of the sulfinic acid products into a range of medicinally relevant functional groups have been developed.
